Regression (or simply failing test): table screen `on_reuse` is not called after scrolling

[andrewhavens]

There are three failing tests which need to be fixed. Either the feature is broken or the tests are broken (I'm not sure yet). These are the tests that are failing:

ProMotion::TableScreen functionality
  - cell has fired on_reuse after scrolling
 [✗] This test has not passed: FAILED - nil.==(true) failed! 
 [FAILED - nil.==(true) failed] 
 BACKTRACE: Bacon::Error: nil.==(true) failed
	spec/functional/func_table_screen_cell_spec.rb:37:in `<main>': ProMotion::TableScreen functionality - cell has fired on_reuse after scrolling

 
  - cell has fired prepare_for_reuse after scrolling
 [✗] This test has not passed: FAILED - nil.==(true) failed! 
 [FAILED - nil.==(true) failed] 
 BACKTRACE: Bacon::Error: nil.==(true) failed
	spec/functional/func_table_screen_cell_spec.rb:55:in `<main>': ProMotion::TableScreen functionality - cell has fired prepare_for_reuse after scrolling


  - should fire prepare_for_reuse before on_reuse
 [✗] This test has not passed: FAILED - not nil.nil?() failed! 
 [FAILED - not nil.nil?() failed] 
 BACKTRACE: Bacon::Error: not nil.nil?() failed
	spec/functional/func_table_screen_cell_spec.rb:67:in `<main>': ProMotion::TableScreen functionality - should fire prepare_for_reuse before on_reuse
